STATIC AND SEISMIC BEHAVIOUR OF DIFFERENT DRY STONE WALL TEXTURES

The mountain architectural heritage built with dry stone technique offers interesting case studies in terms of recov-ery and safeguarding. The variety of case studies, in rela-tionship with the ancient construction technologies, offers focuses for disciplinary insights. The double-facing layer-ing techniques with flat-faced elements, with stone slats that take advantage the mutual meshing of transverse and longitudinal axes, offers interesting resistance situations to dynamic actions not yet fully known. The intuition of the past builders, now can be investigated and to be useful in the recovery of this heritage (for residential uses, e.g.), also in the key to improving their seismic behaviour. This paper describes some in situ tests and possible sustainable solutions to strengthen the original structures (stone walls and roofs, wooden floors) according to current regulations while at the same time preserving their historical and ar-chitectonic values. The masonry texture was characterized by a finite elements modelling of a building case study, in or-der to analyze the seismic behaviour of masonry structures according to the technical standards Italian constructions.
